Answer:
28500
Explanation:
Force equation - F = m * a
F = 950 * 30
F = 28500
Answer:
16
Explanation:
solution:
by taking the ratio of the energy E_n,be of the nth orbit of a beryllium atom
Z_be=4 to the energy E_n,h of the nth orbit of a hydrogen (Z_h=1) atom gives
E_n,B/E_n,H=-(2.18*10^-18)*Z^2_BE/-(2.18*10^-18)*Zh^2/n^2
=Z^2_BE+/Z^2_H
=(4)^2/(1)^2
= 16
Answer:
is to observe through the telescope, study stars inside of the nebula and sometime enhance he pcture to see the real color of the nebula. hopes this helps.
1: a machine makes our work easier
2: a machine can help us find important information
3: a machine can help us transport from a place to another
The object would have a centripetal acceleration <em>a</em> of
<em>a</em> = (12 m/s)² / (0.7 m) ≈ 205.714 m/s²
so that the required tension in the string would be
<em>T</em> = (0.5 kg) <em>a</em> ≈ 102.857 N ≈ 100 N
(rounding to 1 significant digit)
